    Product Overview:

    Pralidoxime Chloride, also known as Pyme chloride, Pralidoxime chloride, etc., is an organophosphate antidote and other rescue drugs, and a cholinesterase reactivator. It is an injection drug, mainly used for the rescue of moderate and severe organophosphorus poisoning, and has good curative effect on parathion, internal absorption phosphorus, methamidophos, and Terp. Its nucleophilic groups can be directly combined with the phosphorylated groups of cholinesterase and then jointly separated from cholinesterase, so that cholinesterase can return to its original state and show vitality again, so as to relieve the symptoms of poisoning. For mild organophosphorus poisoning, it can be used alone to control symptoms; Atropine must be used in combination with moderate and severe poisoning. After intravenous administration, the effective concentration in the blood is quickly reached, and the large dose can also enter the brain tissue through the blood-brain barrier, and is quickly discharged by the kidney, without accumulation of poisoning phenomenon, which has been widely used and generated by a number of drug companies in China.

    Pralidoxime Chloride Powder Usage and Synthesis.

    The quaternary ammonium group can tend to the cationic site of phosphoacylated cholinesterase which has been deactivated by binding with organophosphorus insecticides. Its nucleophilic group can directly bind with the phosphorylated group of cholinesterase and then jointly dissociate cholinesterase, so that cholinesterase can return to its original state and become active again. The "aged" cholinesterase inhibited by organophosphorus insecticides for more than 36h had poor reactivation effect. The e effect on nicotinoid symptoms caused by organophosphus insecticides is obvious, while the E effect on central nervous system symptoms is weak.

    It can replace pralidoxime iodide and revive cholinesterase activity inhibited by acute organophosphorus insecticides to varying degrees, and save the poisoning of many organophosphate insecticides, but it has no revival effect on cholinesterase inhibited by carbamate insecticides, and has poor rescue effect on malathion, trichlorfon, dichlorvos, Dimethoate, mefluron, propylamphos and octamethion poisoning.

    Pralidoxime Chloride Powder

    Drug interaction of Pralidoxime Chloride.

    Praloxime chloride can enhance the biological effect of atropine, so the dosage of atropine should be reduced when the two drugs are used at the same time. The first dose of atropine in general poisoning is 2 to 4mg, once every 10 min. severe poisoning is 4 to 6mg, every 5 to 10min intramuscular or intravenous injection, until atropinization occurs. Atropine should be maintained for 48 hours, and then the atropine dose should be gradually reduced or the injection interval should be extended.

    Pharmacological action of Pralidoxime Chloride.

    Product Method of Bulk Pralidoxime Chloride Powder.

    2-methylpyridine reacted with chloromethane to obtain 2-methylpyridine chloromethane salt, and then nitrified the group with ethyl nitrite to obtain sodium phosphodoxide chloride salt, and then neutralized in ethanol solution with concentrated hydrochloric acid to pH=3-4, filtered sodium chloride, and concentrated ethanol under reduced pressure to obtain crude phosphodoxide chloride, dissolved by distilled water, decolorized by activated carbon, and recrystallized to obtain finished product.
